The Rankine cycle efficiency can be improved with the use of superheating. Which of the following statements is NOT a reason for this improvement?
1
The specific volume of the steam increases, which increases the turbine work output.
2
It increases the average temperature at which heat is added to the working fluid.
3
Superheating reduces the moisture content at the turbine exit.
4
It increases the latent heat of vaporization for the working fluid.
